I am really happy with this purchase. I spent a lot of time researching and was hoping that this would be my most versatile weapon for sport shooting, hunting and home defense. The quality of the 590 is A++. I spent 500+ shells today (various rounds). I had zero jams and .. A LOT of fun. I placed my order online on Thursday and picked it up at Bud's here in Lexington on Tuesday. I can't say enough for the service and professionalism of these guys. Thanks.

I bought this shotgun in September and received in with in a week. I've been holding off on the review because I haven't had a chance to shoot it. Now that I have here are my thoughts.

This 590 Special Purpose shotgun performs flawlessly. From 2 3/4inch shells to the 3inch no feeding problems. Bird shot, double 00 buckshot, triple 000 buckshot, and slugs all fired perfectly and super accurately from this beast.

Changing from stock to pistol grip is self-explanatory. I prefer to keep the pistol grip on when keeping it around the house. However when I am out doors I prefer the stock. Obviously using the pistol grip makes it kind of hard to shoot and it hurts the hand. Overall though it's a very fun experience with either one.

Now I did have a HUGE problem with this shotgun when it came to disassembly. The magazine cap is supposed to unscrew by hand. However I found it IMPOSSIBLE to unscrew. I had to use a set of pliers with rubber to get this thing off. Once I did get it off I examined the cap and the tube and they seemed to be in perfect condition. Screwing it back on required the pliers again. This is unacceptable. I did some research and as it turns out the spring retainer cause the magazine tube to expand, which is why it's to hard to screw the cap on. I took that off and have had no problems since. It screws on like it should.

Perfect shotgun minus the spring retainer problem, which is an easy fix. 5 star service from buds. If I ever decide to buy another gun, this is the place for me.

If you have this problem with your shotgun just get rid of the spring retainer in the magazine tube. Yeah it's nice but it's not worth it. The tube is aluminum and the retainer is steel. Obviously this is causing the tube to expand enough to make it a problem.

Anyways I am in love with my shotgun and could not be happier. I even added a mariner heat shield that I also bought here from buds. Word of advice, the mariner heat shield sold on this site is not really designed for this particular mossberg shotgun model. I mean it will still fit but don't expect the screws to work. Either way it doesn't need screws since it's a pretty tight fit to get it on there. It's pretty secure. I did scratch the barrel a bit while putting it on but nothing major. Just be careful if you do decide to add a heat shield and do some research on getting the proper one if you are looking to do things by the book.
